I just made a quick test with SBCL 0.9.12 on x86-64 and had to change
one line in pygetarg from

   (string (cffi:foreign-string-to-lisp (cffi:mem-ref variable :string)))

to

   (string (cffi:mem-ref variable :string))

Someone else posted that everything worked fine for him with a very
similar configuration, so I *guess*, that it might be a change between
different CFFI versions. I ASDF-INSTALLed it a few weeks ago and it is
version 0.9.1. Maybe cvs CFFI is different in this regard?
